The easiest way to find the inverse of a function is to swap the x and y, meaning:
We have the function
. Let's call our outputs "y", so we have 
. To find the inverse, we're going to change the x and the y's position in the equation, so we have 
. Then all we need to do is solve for y:
We have the function
